I have dataset A and B.
I want to lookup dataset A (Column X) into dataset B (column Y).
If dataset B(Col Y row) contains the string(not a full match, just if its exists in Col Y) from dataset A (column X) , then keep that row in dataset B.
Ie Dataset A column X.
Does this exist in Databset B Col Y.
If it exists return dataset B rows which match this logic.
